Why Zernio

Two ways to post to Telegram. One of them you maintain

Zernio API

  • Simple API key auth

    Get posting in 30 seconds. No bot tokens, no webhook server.

  • Automatic flood control

    Built-in queuing, retries, and rate limit management.

  • One endpoint for all media

    Text, photos, videos, documents. Same payload structure.

  • Zero maintenance

    We absorb Bot API changes. Your code never breaks.

  • 15 platforms, one API

    Same integration posts to Telegram, Instagram, LinkedIn, and 12 more.

Telegram Bot API

  • Complex bot token management + webhook setup

    Create bot via BotFather, manage tokens, spin up webhook server.

  • Strict flood control

    30 messages/second globally, 1 msg/second per chat. Manual throttling.

  • Multiple endpoints for different media

    sendMessage, sendPhoto, sendVideo, sendDocument. Each has its own params.

  • Manual error and update handling

    Poll for updates or manage webhook callbacks. Handle errors yourself.

  • Per-platform silos

    Each social network needs its own SDK, auth flow, and maintenance.

“Zernio is great.”

What the API does

Publishing, analytics and SDKs in one Telegram API

One sk_ key. One payload shape. No Bot API tokens, no webhook server.

Publish and schedule

Post text, images, and video to Telegram channels and groups.

  • One payload shape for text, images, video
  • Immediate publish or scheduled send
  • Drafts + recurring queues

Read the numbers

Per-post and per-account metrics from the same integration that publishes them.

  • Engagement rate
  • Reach and impressions
  • Follower stats
  • Per-post and per-account

Run the DM thread

The richest DM surface Zernio exposes, in the same multi-channel inbox.

  • Attachments, buttons, quick replies
  • Edit, quote-reply, archive
  • Multi-channel inboxes

Telegram caveat we do not hide: Telegram bots can only DM a user who messaged the bot first. That is a Bot API rule, not a Zernio limit. Channel and group posting is unrestricted where the bot is admin.

What developers say after shipping

  • Elena Zarino
    Elena Zarino Web Developer

    I integrated Zernio's API and MCP into my Claude Copilot and Claude Code setup, and it filled a gap I'd been working around for a while.

  • Leon

    We're integrating Zernio into our coaching app's WhatsApp inbox and love how clean the SDK is. Thank you for that.

  • Justin
    Justin Founder, StandoutResults

    We'd been using the HighLevel API for social posting, every post stuck in draft, a lot of hassle. Zernio has been a breeze to work with.

  • Marko
    Marko Developer, Meta Ads API

    It works flawlessly now. Superb, as always. You and the team rock, keep up the amazing work.

  • Razvan Ghetiu

    I spent a long time looking for a simple way to integrate a self-hosted stack. Zernio was just perfect, and I highly recommend it.

FAQ

Common questions

Why use Zernio instead of the Telegram Bot API?

The Bot API requires creating a bot via BotFather, managing tokens, setting up webhook servers or polling for updates, and handling flood control manually. Zernio abstracts all of this behind a single API key. You get posting in 30 seconds.

Can I send direct messages?

Telegram bots can only message users who have started a conversation with the bot first. Zernio focuses on channel and group posting. For channels and groups where the bot is admin, you can post freely.

What media types are supported?

Text messages (up to 4096 characters), photos (JPEG, PNG, WebP), videos (MP4, up to 50MB), and documents (any file type). All through the same endpoint with the same payload structure.

How are rate limits handled?

Telegram enforces strict flood control: 30 messages/second globally and 1 message/second per chat. Zernio automatically manages this with intelligent queuing so your messages are delivered reliably.

How does authentication work?

One Zernio API key is all you need. Behind the scenes, Zernio manages bot tokens and permissions. Your users connect their Telegram channel or group once, and you get posting access immediately.
